Keyue Smedley recognized for contributions to electrical engineering
Keyue Ma Smedley, Ph.D., professor of electrical engineering and computer science in The Henry Samueli School of Engineering at UC Irvine, has been elected a Fellow of the
Smedley's research focuses on electronic circuits for high current and high voltage power processing. This is a critical area covering all electrical applications large and small, from cell phones to utility power grids. Her groundbreaking work on one-cycle control led to professional audio amplifiers one-seventh the size of previous models with a ten-fold efficiency improvement in 1998, and a unified controller for three-phase
Recently, Smedley’s research team has made another breakthrough in topology and control of medium-voltage power conversion with a circuit called a hexagram, which extends the operating range of commercially available semiconductor devices to megawatt power circuits. The hexagram converter can be used to drive megawatt motors with high efficiency and high precision for manufacturing, transportation, and power plant applications. Smedley continues to focus on power electronics for renewable power generation and modern grids to reduce the green house effect and fossil fuel consumption.
Smedley received her B.S. and M.S. degrees in electrical engineering from
